Blinking Volume lights in HomePod

Sorry you can’t get it to reset. It’s a serious hardware failure. The repair or replace by Apple is not worth the cost due to expired warranty . Almost as much as a new one. This is honestly the only options I or we have for you to get it working. Good luck!

• Also if you have other HomePods that are exhibiting strange behaviour such as loud popping sounds, do try the instructions I provided above to fix it before they go the blink. And update the software one at a time, at your own risk and check each one works before updating the next. That’s what I do

This issue can be difficult to fix. In some cases the following instructions may help:

• start by unplugging it for over 24 hrs
• Plug back in

1. Unplug HomePod again or unplug the power adapter for HomePod mini, wait 10 seconds, then plug HomePod back in.
2. Wait 10 seconds, then touch and hold your finger to the top of HomePod.
3. The white spinning light will turn red. Keep your finger down. 
4. Siri will say that your HomePod is about to reset. When you hear three beeps, you can lift your finger.

• After you reset HomePod, you can set up HomePod again.
